Connection Method, Communication System, Mobile Terminal, Information Forwarding Device, and Server

1. A connection establishment method by which a mobile terminal connects to a local connection service provided in a moving body, the moving body having an information forwarding device and a storage server connected to the information forwarding device, the information forwarding device being an access point of the mobile terminal to forward information to the mobile terminal, the storage server storing contents and cached data, the method comprising: sending, by the mobile terminal, preference information regarding a user of the mobile terminal before the mobile terminal connects to the information forwarding device; determining, by the information forwarding device, based on the preference information, whether the contents or the cached data stored in the storage server are appropriate for the user of the mobile terminal; sending a result of the determining to the mobile terminal before the mobile terminal connects to the information forwarding device; and when the mobile terminal becomes connectable to the information forwarding device, not connecting the mobile terminal to the information forwarding device if the connects or the cached data stored in the storage server are not appropriate for the user of the mobile terminal based on the result, and connecting the mobile terminal to the information forwarding device if the contents or the cached data stored in the storage server are appropriate for the user of the mobile terminal based on the result.

2. The connection establishment method according to claim 1 , wherein the preference information regarding the user of the mobile terminal and the result from the information forwarding device are transmitted through a WAN connection.

3. The connection establishment method according to claim 1 , further comprising; holding, by a server, neighborhood information regarding another information forwarding device to forward the preference information to, the information forwarding device being a device to which the mobile terminal is going to connect, before the mobile terminal connects to the other information forwarding device.

4. A communication system in which a mobile terminal connects to a local connection service provided in a moving body, the moving body having an information forwarding device and a storage server connected to the information forwarding device, the information forwarding device being an access point of the mobile terminal to forward information to the mobile terminal, the storage server storing contents and cached data, the system comprising: first communication circuitry in the mobile terminal, which in operation sends preference information regarding a user of the mobile terminal before the mobile terminal connects to the information forwarding device; connection acknowledgment circuitry in the information forwarding device, which in operation determines, based on the preference information, whether the contents or the cached data stored in the storage server are appropriate for the user of the mobile terminal; second communication circuitry coupled to the connection acknowledgment circuitry in the information forwarding device, which in operation sends a result of processing performed by the connection acknowledgement circuitry to the mobile terminal before the mobile terminal connects to the information forwarding device; and connection confirmation circuitry coupled to the first communication circuitry in the mobile terminal, which in operation, when the mobile terminal becomes connectable to the information forwarding device, does not cause the mobile terminal to connect to the information forwarding device if the contents or the cache data stored in the storage server are not appropriate for the user of the mobile terminal based on the result, and causes the mobile terminal to connect to the information forwarding device if the contents or the cached data stored in the storage server are appropriate for the user of the mobile terminal based on the result.

5. The communication system according to claim 4 , further comprising: holding circuitry, in a server, which in operation holds neighborhood information regarding another information forwarding device to forward the preference information to, the information forwarding device being a device to which the mobile terminal is going to connect, before the mobile terminal connects to the other information forwarding device.

6. An information forwarding device installed in a moving body as an access point of a mobile terminal to forward information to the mobile terminal in a communication system in which the mobile terminal connects to a local connection service provided in the moving body, the device comprising: first communication circuitry, which in operation receives preference information regarding a user of the mobile terminal sent by the mobile terminal before the mobile terminal connects to the information forwarding device; and connection acknowledgment circuitry coupled to the first communication circuity, which in operation determines based on the preference information, whether contents or cached data stored in a storage server connected to the information forwarding device are appropriate for the user of the mobile terminal, when the mobile terminal becomes connectable to the information forwarding device, wherein the first communication circuitry in operation sends a result of processing performed by the connection acknowledgment circuitry to the mobile terminal before the mobile terminal connects to the information forwarding device, the result indicating approval of connection when the connection acknowledgment circuitry determines the contents or cached data stored in the storage server are appropriate for the user of the mobile terminal, and the result indicating disapproval of connection when the connection acknowledgment circuitry determines the contents or cached data stored in the storage server are not appropriate for the user of the mobile terminal; and forwards the information to the mobile terminal when the mobile terminal connects to the information forwarding device.

7. A mobile terminal for connecting to a local connection service provided in a moving body, the moving body having an information forwarding device and a storage server connected to the information forwarding device, the information forwarding device being an access point of the mobile terminal to forward information of the mobile terminal, the storage server storing contents and cached data, the terminal comprising: communication circuitry, which in operation sends perference information regarding a user of the mobile terminal before connecting to the information forwarding device; and receives a result sent by the information forwarding device before connecting to the information forwarding device, where the result is based on the preference information as to whether the contents or the cached data stored in the storage server are appropriate for the user of the mobile terminal; and connection confirmation circuitry coupled to the communication circuitry, which in operation, when the mobile terminal becomes connectable to the information forwarding device, does not cause the mobile terminal to connect to the information forwarding device if the contents or the cached data stored in the storage server are not appropriate for the user of the mobile terminal based on the result, and causes the mobile terminal to connect to the information forwarding device if the contents or the cached data stored in the storage server are appropriate for the user of the mobile terminal based on the result.

8. The connection establishment method according to claim 1 , wherein the preference information is information regarding contents of interest to the user of the mobile terminal or contents the user is scheduled to use, or information regarding a history of contents data accessed or Web accesses made in the past.

9. The information forwarding device according to claim 6 , wherein the preference information is information regarding contents of interest to the user of the mobile terminal or contents the user is scheduled to use, or information regarding a history of contents data accessed or Web accesses made in the past.

10. The mobile terminal according to claim 7 , wherein the preference information is information regarding contents of interest to the user of the mobile terminal or contents the user is scheduled to use, or information regarding a history of contents data accessed or Web accesses made in the past.
